Gray Morrison with the Phoenix Branch, shared some information from a project their team is working on:
One of our customers has a large number of critical sites that connect their customers to the internet, and provide phone and cable service and have been receiving modernized telecom equipment over the past few years. The new equipment generates an impressive amount of heat. The most notable device, the Cisco CBR8 router, produces 2.5 tons of heat per device. The goal of our projects is to increase the cooling capacity through new Stulz RTUs and ductwork expansion in each site. None of the Customer’s critical sites were designed for this amount of heat or power, so our Customer trusted my team to design and build solutions to get them through the foreseeable future of the rapidly changing telecom business.
At one of our Customer’s sites we had to double the number of 25 ton air conditioners, and double the amount of ductwork in a very crowded space. In a well-coordinated effort we cut three large holes in the roof to add the RTUs, exposing a highly critical site to the elements while we installed structural steel to support the new air conditioners. It was very high risk work at times, but DP Air is no stranger to demanding projects. The ductwork installation is very tedious due to the amount of power and communication cabling overhead. Despite this we were able to add up to 20 tons of cooling per cold aisle in the high heat density area.
A big thank you to Dan Walker and his team, specifically Paul Pullenza and David Debruyne, who have brought the projects in on budget and on time. The feedback from the Customer is that they have never had as positive of an experience on critical infrastructure projects than with DP Air. We have solidified ourselves as our Customer’s specified mechanical design build team thanks to everyone from the field team at the Phoenix branch!
